The snow-melting areas include the following:
* Stainless steel 3 mm containers with reinforcing ribs and bracings that also serve as splitters of the
snow bulk, and cleaning windows on the back side
* Coiled cylindrical heat exchangers of nominal diameter with ribs for enhancing heat capacity and
structural stiffness (submerged horizontally into the water by its most part) providing snow heating and
water generating after snow melting. Heat exchangers serve as combustion chambers of the liquid
(diesel) fuel and made out from stainless steel of various quality and thickness. Handles of diesel burners
are inserted into the heat exchangers through the hole in a bracing between the control area and melting
container. The fastening of the heat exchanger is performed by bolts through a flange on heat exchanger
housing and on a flange with studs on the bracing. Tightness is provided by two seals on the flanges. To
avoid sagging the reinforcing ribs of heat exchangers are fixed to the cylindrical rack by bolts located
over the heat exchangers. The heat exchanger output consists of special exhaust manifold of output
gases with a relief valve directing the output gas flow along the line of melted water that allows using gas
energy for additional melting of the snow over the water surface.
* Two pumping compartments located symmetrically from the both sides of the melting containers that
include pumps connected to the snow irrigation system. Tapering bottoms of the compartments have
valves performing mud water drainage.
Irrigation System:
*Consists of the stainless steel L-shaped lines (manifold) ending with plugs for cleaning and is connected
to pumps. It is designed for irrigation of the snow over the water surface by heated water for enhancing of
operation efficiency.
Filtration and water drainage areas:
*Consists of a duct rigidly connected to the melting container. The deliverance is provided due to the
window with a steel grid in the melting container wall. The bottom of the duct includes windows for
cleaning and a drainage line. The upper part contains the cover for the maintenance service.
Filtration chamber:
* It is designed in a form of a trapezoidal duct. The snow melting container is divided by a bracing with
rectangular hole for melted water drainage that is located over the plane of mechanical protection. The
steel grid is used to separate the filtration area from the floating objects. The filtration area is divided by
the bracing into two areas: the area for collection mechanical sediments and drainage area. There is
water drainage and cleaning hole at the bottom of the filtering chamber.
Operational modes:
* The manual mode implies switching of the machine on by the operator and continuous operation of
diesel burners at full power;
* The automatic mode implies use of timer for switching heat generating unit on and off (cycle);
*Drainage of the water from the snow-melting container after operation is provided by the stop valve.
*The control panel, pump and heat generating units as well as fuel tanks are located in separate
compartments of the machine and protected from mechanical damage.
Operationing principle:
*The component part of the machine includes the heat generating unit (gas or diesel burner) located in a
separate housing, snow melting container, filtration and melt water drainage area.
*The flow of hot exhaust gases from the heat generating unit is directed along the coiled heat exchanger
installed horizontally with regard to the snowmelt container. The heated gas moving in the turbulent flow
generated due to peculiarities of internal structure of the heat exchanger heats the walls that transfer the
heat to the water (snow) around the heat exchanger.
*The heated water layers create an upward flow that carries the warm water and transfers the heat to
loaded snow. To increase efficiency of flow mix and corresponding heat transfer from the heated layers
the machine uses the system of forced feed of heated melt water (pumps and irrigation system).
*The exhaust gases at the top of the heat exchanger being significantly cooled but still having the
temperature above the temperature of the environment escape to the atmosphere through the special
manifold. This manifold allows using additionally the heat of the exhaust gases by generating an air-heat
curtain over the snow bulk. There is no direct contact of the melt water as opposed to the foreign
counterparts, and it is an advantage from the ecological viewpoint.
*The melt-water overflows through the special outlet into the filtration area where it is partly cleaned from
solids (sand, fine litter). Drainage of the melt-water is carried out via the drainage pipe into the storm
sewage system. Sand sediments fall on the melting container bottom. After operation cycle is finished the
contained is cleaned from sediments through the sealed holes located at the back side of the machine
near the drain.
Tonnage Rates :
Snow-melters are rated at tons of snow per hour at 30° degrees F. That is the Snow-melter will melt X
amount of tons of pure snow with an incoming snow temperature of 30° F. If the incoming snow temperature
is -4° F, this will result in an additional heat requirement of BTU’s just to raise the temperature of the snow
to the melting point. If the nominal capacity of the Snow-melter is to be maintained, then an additional heat
input per hour is required. There is no margin in the burners to allow for this extra heat requirement. The
burners are designed to operate continuously at their rated input, thus any decrease in incoming snow
temperature will result in a de-rating of the Snow-melter. The other major factor which will cause a de-rating
is ice, the surface area of a quantity of ice compared with snow is very small and the heat transfer rate is
lower, such that it will take longer to melt a pound of ice compared with a pound of snow. Snow-melters use
Submerged Combustion Technology, the most efficient and time tested technology available, requiring only
1.2 US Gallons of diesel to melt 1 - ton of snow.
